Zs a little out, what can I do to fix it?

[Inteificio]

Hi.

Am working in a factory, most of the machinery on the main floor is fed from are fed from spurs (2/3 machines per spur).

As they have all been fitted with D type breakers, we need a tight Zs.
We have not got it.

I am trying to think of the easiest way of fixing it.
Turns out I'm not 100% sure what you can do with CPCs.

If each circuit has it's own dedicated CPC, can I also link a supplementary CPC (or even make a link between each CPC to have a star supplementary earth in addition to the original?)
I've flicked through the regs and can't find any info on supplementary earths!

The way I read it, is as long as all the CPCs are in the same enclosure you can do what you want!

Anyone with a bit more experience got a few tips?

Thanks,

RCD would be a simple solution, but we have a VERY limited budget at the moment.

The wiring is in plastic trunking on a floating ceiling, so not much to bond up there with a good connection.

I'm thinking linking all those earths is the cheapest, easiest solution.

I will see how that goes then, if problems, work out what to do next.

To solve your problem in the most efficient and best way, you should contact an expert to do it. They will check it up and could fix the damage as well. If you will do it by yourself, then there is a big possibility that you get to risk.

Thanks for the useful input ;-)

Like using larger CPC's from the DB!! ...lol!!!

We are very limited on space, and that would be 1 hell of a job. Linking the CPCs will have a far greater effect for less time and materials.

The last thing I want to do is be dragging in huge amounts of wire down 20mm copex.

Hopefully yes!!, but my reply was based on your comment....

In other words, if it doesn't provide the necessary results!! lol!!
